Separation of a vortex in B point comes after a hemispheroid
[T/2] by the separation of the vortex from A point, thereby is produced the vortex sheet placed behind the cylinder.
The volume of nests was calculated from height (h) and basal radius (r) using the formula for the volume of a hemispheroid
when h [less than] r:
